推荐答案

除了执行两次POST之外，您还可以执行以下操作:

Instead of doing a double POST, you can do something like this:

function readURL(input) { if (input.files && input.files[0]) { var reader = new FileReader(); reader.onload = function(e) { $('#blah').attr('src', e.target.result); } reader.readAsDataURL(input.files[0]); } } $("#imgInp").change(function() { readURL(this); });

<script src="ajax.googleapis/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <form id="form1" runat="server"> <input type='file' id="imgInp" /> <img id="blah" src="#" alt="your image" /> </form>

请记住，仅因为您选择了要上传的文件并不意味着该文件已上传.服务器仍然没有收到数据，因此，从客户端收集数据要比我想做的要有意义.

Remember, that just because you've selected a file to upload doesn't mean its been uploaded. The server still hasn't received the data, thus, doing this on the client side makes a little more sense from what i gather you want to do.
